How to find the area of a rhombus with one diagonal and perimeter?.

Answers

Answer 1

The area of rhombus can be found using the formula A = (d1 x d2)/2, where d1 and d2 are the lengths of the diagonals. Using area formula, we get A = (24 x 18)/2 the area of the rhombus is 24√(119) square meters.

Let's start by finding the other diagonal of the rhombus.

We know that the perimeter of a rhombus is four times the length of one of its sides. So, if the perimeter is 80 m, then each side has a length of 80/4 = 20 m.

We also know that the diagonals of a rhombus are perpendicular bisectors of each other, and they divide the rhombus into four congruent right triangles. Therefore, each leg of one of these right triangles is half of one of the diagonals of the rhombus.

Let's call the other diagonal of the rhombus d. Then, using the Pythagorean theorem in one of the right triangles, we have

(20/2)² + (d/2)² = 24²

100 + d²/4 = 576

d²/4 = 476

d = 2√(119)

Now that we have both diagonals, we can find the area of the rhombus by multiplying them and dividing by 2

Area = (24 * 2√(119))/2

Area = 24√(119)

Therefore, the area of the rhombus is 24√(119) square meters.

Using logarithms, you determined the of 7 solutions ranging from strong acid to neutral to strong base.

Answers

Logarithms are a useful tool in determining the acidity or basicity of a solution. pH is a measure of the concentration of hydrogen ions in a solution and is calculated using the formula pH = -log[H+].

A solution with a pH of 7 is considered neutral, while a pH below 7 indicates acidity and a pH above 7 indicates basicity.

Using logarithms, we can determine the pH of 7 solutions ranging from strong acid to neutral to strong base. To do this, we need to measure the concentration of hydrogen ions in each solution and then use the formula above to calculate the pH.

For example, if we have a solution with a hydrogen ion concentration of 0.001 M, we can calculate the pH as follows:

pH = -log(0.001) = 3

This solution would be considered a strong acid, as it has a pH below 7. Similarly, a solution with a hydrogen ion concentration of 10^-7 M (which is the same as a concentration of 1x10^-7 M) would have a pH of 7 and would be considered neutral.

Finally, a solution with a hydrogen ion concentration of 10^-11 M would have a pH of 11 and would be considered a strong base.

In summary, using logarithms, we can determine the acidity or basicity of a solution by calculating its pH. A pH of 7 is considered neutral, while a pH below 7 indicates acidity and a pH above 7 indicates basicity.

Is it true that If B is produced by interchanging two rows of A, then detB = detA.

Answers

No. It is not true that if B is produced by interchanging two rows of A, then detB = detA.

det(B) = -det(A) is the correct formula for calculating the determinant of a matrix obtained by interchanging two rows of another matrix.

Two rows of a matrix are interchanged, the determinant of the resulting matrix is equal to the determinant of the original matrix multiplied by -1.

Therefore, we have det(B) = -det(A).

This can be seen from the formula for calculating the determinant of a matrix.

When two rows are interchanged, the determinant of the resulting matrix is equal to the determinant of the original matrix multiplied by -1 raised to the power of the number of row interchanges.

Since we have interchanged two rows, the power is 2, so the determinant of the resulting matrix is equal to the determinant of the original matrix multiplied by (-1)² = 1.

det(B) = -det(A) is the correct formula for calculating the determinant of a matrix obtained by interchanging two rows of another matrix.

a super recipe uses 1 1/2 cups of water for every 1/4 teaspoon of seasoning if a large a batch of soup is made using 1 teaspoon of seasoning how many cups of water is needed?

Answers

Answer:

Step-by-step explanation:

First, we need to figure out how many 1/4 teaspoons are in 1 teaspoon:

1 teaspoon = 4 (1/4) teaspoons

So for 1 teaspoon of seasoning, we need:

1 teaspoon seasoning * 1 1/2 cups water per 1/4 teaspoon seasoning

= 4 (1/4) teaspoons seasoning * 1 1/2 cups water per 1/4 teaspoon seasoning

= 6 cups of water

Therefore, if a large batch of soup is made using 1 teaspoon of seasoning, we would need 6 cups of water.

western lowland gorillas, whose main habitat is the central african continent, have a mean weight of 275 pounds with a standard deviation of 40 pounds. capuchin monkeys, whose main habitat is brazil and a few other parts of latin america, have a mean weight of 6 pounds with a standard deviation of 1.1 pounds. both weight distributions are approximately normally distributed. if a particular western lowland gorilla is known to weigh 345 pounds, approximately how much would a capuchin monkey have to weigh, in pounds, to have the same standardized weight as the lowland gorilla?

Answers

To find the capuchin monkey's weight with the same standardized weight as the lowland gorilla, we need to first calculate the z-score of the gorilla's weight.

The z-score represents how many standard deviations a data point is away from the mean.

For the gorilla with a weight of 345 pounds, the z-score can be calculated as follows: Z-score = (Weight - Mean) / Standard Deviation
Z-score = (345 - 275) / 40 = 70 / 40 = 1.75.

So a gorilla weighing 345 pounds has a standardized weight of 1.75 standard deviations above the mean. Now we need to find out how much a capuchin monkey would have to weigh to have the same standardized weight.

We can use the same formula and solve for x: z = (x - mean) / standard deviation .


1.75 = (x - 6) / 1.1
1.925 = x - 6
x = 7.925



So a capuchin monkey would have to weigh approximately 7.925 pounds to have the same standardized weight as a gorilla weighing 345 pounds. It's important to note that standardized weights are not the same as actual weights.

They are simply a way to compare values from different distributions on a common scale.

Now that we have the z-score, we can use it to find the capuchin monkey's weight with the same standardized weight: Weight = Mean + (Z-score × Standard Deviation), Weight = 6 + (1.75 × 1.1) = 6 + 1.925 = 7.925.


Therefore, a capuchin monkey would have to weigh approximately 7.93 pounds to have the same standardized weight as the lowland gorilla.

Answers

The F statistic for this data set is 1.93, with a p-value of 0.098. This means that we cannot reject the null hypothesis that there is no difference between the means of the cities at a significance level of 0.05.

Therefore, we cannot conclude that there is a significant difference in hotel costs per night between the five cities.

To find the value of the test statistic to test for a difference between cities, we need to perform a statistical test such as a one-way ANOVA (analysis of variance) test. This test compares the variation between the means of multiple groups to the variation within each group. The test statistic for a one-way ANOVA is F.

To calculate the F statistic, we need to first find the sum of squares within groups (SSW) and the sum of squares between groups (SSB). SSW measures the variation within each group and SSB measures the variation between groups.

SSW = ∑(xi – xj)² / df_within

where xi is the value of each observation, xj is the mean of each group, and df_within is the degrees of freedom within groups, which is equal to the total number of observations minus the number of groups.

SSB = ∑(xj – xbar)² / df_between

where xbar is the grand mean of all the observations, and df_between is the degrees of freedom between groups, which is equal to the number of groups minus one.

Once we have calculated SSW and SSB, we can calculate the F statistic as:

F = SSB / df_between / (SSW / df_within)

If the F statistic is greater than the critical value from the F distribution table, we can reject the null hypothesis that there is no difference between the means of the groups.

In this case, we have five cities: New York, Los Angeles, Atlanta, Houston, and Phoenix. We can use Excel or another statistical software to calculate the ANOVA test.

The F statistic of 1.93 and the associated p-value of 0.098 indicate that we cannot reject the null hypothesis at a significance level of 0.05. This suggests that there is no significant difference in hotel costs per night among the five cities: New York, Los Angeles, Atlanta, Houston, and Phoenix. The analysis was performed using a one-way ANOVA test, comparing the variation between the means of the cities to the variation within each city.

Un triangulo con 2 lineas que sus 3 angulos midan 90 grados

Answers

The measures of the angles in the triangle are 30 degrees, 60 degrees, and 90 degrees.

In this case, we are given that the angles of the triangle are in the ratio of 1:2:3. This means that the three angles can be expressed as x, 2x, and 3x, where x is some constant factor.

To find the value of x, we need to use the fact that the sum of the angles in a triangle is 180 degrees. So, we can write an equation:

x + 2x + 3x = 180

Simplifying the equation, we get:

6x = 180

Dividing both sides by 6, we get:

x = 30

Now that we know the value of x, we can use that to find the measure of each angle in the triangle.

The first angle is x, which we know is 30 degrees.

The second angle is 2x, which is 2 times 30, or 60 degrees.

The third angle is 3x, which is 3 times 30, or 90 degrees.

What is fraction?

A fraction is a mathematical term that represents a part of a whole or a ratio between two quantities. It is a way of expressing a number as a quotient of two integers, where the top number is called the numerator, and the bottom number is called the denominator.

By the multiplicative property of the Legendre symbol, we know that $(\frac{-2}{p}) = (\frac{-1}{p}) (\frac{2}{p})$.

We have $(\frac{-1}{p})=(-1)^{\frac{p-1}{2}}$. Therefore, $(\frac{-1}{p})=1$ if $p\equiv 1\pmod{4}$, and $(\frac{-1}{p})=-1$ if $p\equiv 3\pmod{4}$.

To evaluate $(\frac{2}{p})$, we use the quadratic reciprocity law. We have $(\frac{2}{p})=(-1)^{\frac{p^2-1}{8}}(\frac{p}{2})$, where $(\frac{p}{2})$ is the Legendre symbol.

We have $(\frac{p}{2})=1$ if $p\equiv \pm 1\pmod{8}$ and $(\frac{p}{2})=-1$ if $p\equiv \pm 3\pmod{8}$.

Therefore, $(\frac{2}{p})=(-1)^{\frac{p^2-1}{8}}(\frac{p}{2})$ is equal to $1$ if $p\equiv \pm 1\pmod{8}$ and $-1$ if $p\equiv \pm 3\pmod{8}$.

Putting it all together, we have $(\frac{-2}{p}) = (\frac{-1}{p}) (\frac{2}{p}) = 1$ if $p\equiv 1\pmod{4}$ and $p\equiv \pm 1\pmod{8}$, and $(\frac{-2}{p}) = (\frac{-1}{p}) (\frac{2}{p}) = -1$ if $p\equiv 3\pmod{4}$ and $p\equiv \pm 3\pmod{8}$.

Therefore, we can conclude that $(\frac{-2}{p})=1$ if and only if $p\equiv \pm 1\pmod{8}$, and $(\frac{-2}{p})=-1$ if and only if $p\equiv \pm 3\pmod{8}$.

In a random sample of ten cell​ phones, the mean full retail price was ​$450.50 and the standard deviation was ​$206.00. Assume the population is normally distributed and use the​ t-distribution to find the margin of error and construct a 95​% confidence interval for the population mean mu. Interpret the results. Identify the margin of error. nothing ▼ ​(Round to one decimal place as​ needed.)

Answers

To find the margin of error for a 95% confidence interval using the t-distribution, we first need to calculate the t-score with degrees of freedom (df) equal to the sample size minus 1 (n-1).

In this case, df = 9. Using a t-table or calculator, the t-score for a 95% confidence level and df = 9 is approximately 2.262. The margin of error can be calculated by multiplying the t-score by the standard error of the mean, which is equal to the standard deviation divided by the square root of the sample size.

In this case, the standard error of the mean is 206 / sqrt(10) = 65.20. Multiplying by the t-score, we get a margin of error of 2.262 * 65.20 = 147.54. To construct the 95% confidence interval, we can use the formula:
sample mean +/- (t-score * standard error of the mean)



Substituting in the values, we get:
$450.50 +/- (2.262 * $65.20) = $450.50 +/- $147.54

So, the 95% confidence interval for the population mean mu is $302.96 to $598.04.

Interpreting the results, we can say with 95% confidence that the true population mean full retail price of cell phones is between $302.96 and $598.04. The margin of error is the amount by which the sample mean may differ from the true population mean, and in this case it is +/- $147.54.


The 95% confidence interval for the population mean (µ) is ($304.1, $596.9), and the margin of error is $146.4. This means we can be 95% confident that the true population mean price of cell phones is between $304.1 and $596.9.

Answers

From the phenotypic variance (p) of the genetically variable and genetically identical plants, the value of the broad-sense heritability (H) of seed number for the roadside population of bluebonnets is equals to the 0.6.

We have, population of graduation studying students in bluebonnets along a roadside. Sample size of plants = 100

variance for plants = 25

=> standard deviations = 5

We have to determine the broad-sense heritability (H) of seed number for the roadside. Broad-sense heritability [tex]H2 = \frac{V_G }{ V_P} [/tex] ---(1)

The phenotypic variation [tex]V_P = V_G + V_E [/tex], here [tex] V_P = 25[/tex]

[tex]25 = V_G + V_E[/tex] ------(II)

In the identical population, [tex] V_G = 0[/tex] and here [tex] V_P = 10[/tex]

=> [tex]10 = 0 + V_E [/tex]

=> [tex]V_E= 10[/tex]

By substituting [tex]V_E[/tex] value in equation (II), we will determine [tex]25 = V_G + 10 [/tex]

=> [tex]V_G = 15[/tex]

Substitute the values of [tex]V_G and V_E [/tex] of the roadside population in equation (1), [tex]H²=\frac{15}{25}=0.6[/tex].

The key to the answer is assumption should be the genetic variance of the genetically identical plants is the same as the genetically variable population. In the event that we don't make this supposition, at that point our concern turns out to be very entangled in light of the fact that then we should likewise realize the genetic variance effect of the plant in its environment as well.

a. In your own words, describe to someone who knows only a little statistics how to recognize when an observation is an outlier. What action(s) should be taken with an outlier?
Choose the best answer below.
A. Outliers are the minimum and maximum values observed in a data set. They should be treated as any other value, as the term "outliers" is just another
B. Outliers are observed values far from the main group of data. In a histogram they are separated frorm the others by space. Outliers should be ignored name for the minimum and maximum. because they can distort any calculations done and are not representative of typical values closer context to know how to treat them. If they are mistakes, they might be removed or corrected. If they are not mistakes, you might do the analysis
C. Outliers are observed values far from the main group of data. In a histogram they are separated from the others by space. Outliers must be looked at în twice, once with and once without the outliers.
D. Outilers are observations that are more than 1 5 interquantle anges from the median in a data set They should be looked at in closer context to determine how to treat the values. Sometimes they may be included, but sometimes they are discarde
b. Which measure of the center (mean or median) is more resistant to outliers, and what does "resistant to outliers" mean?
Choose the best answer below.
A. The median is more resistant, which indicates that it usually changes less than the mean when comparing data with and without outliers
B. The median is more resistant, which indicates that neither the number nor the magnitude of outlers has any effect on the calculated value ofthe median
C. The mean is more resistant, which indicates that it is easier to calculate when there are outliers present than the median is.
D. The mean is more resistant, which indicates that it usually changes less than the median when comparing data with and without outliers

Answers

a.  Outliers are observed values far from the main group of data.

In a histogram they are separated from the others by space.

Outliers must be looked at twice, once with and once without the outliers. C.

b. The median is more resistant, which indicates that it usually changes less than the mean when comparing data with and without outliers. A.

Outliers are data points that are significantly different from the other values in a data set.

These observations can be identified by looking at a histogram, where they are separated from the main group of data by a significant space.

Outliers can be mistakes or they may represent real but unusual values.

It is important to look at outliers in closer context to determine how to treat them.

Sometimes they may be included in the analysis, but other times they may be removed or corrected.
To determine which measure of center, mean or median, is more resistant to outliers, we need to understand what "resistant to outliers" means.

Resistance to outliers refers to how much a measure of center is affected by the presence of outliers.

A measure that is more resistant to outliers will change less when outliers are present.
The median is more resistant to outliers than the mean.

This means that the median usually changes less than the mean when comparing data with and without outliers.

The reason for this is that the median is calculated by taking the middle value of the data set, which is less affected by extreme values than the mean, which takes into account all values in the data set.
Outliers should be examined carefully in the context of the data set to determine how to treat them.

The median is more resistant to outliers than the mean, which makes it a better measure of center when outliers are present.

Which explicit formula can be used to illustrate the sequence below?



6, 12, 24, 48, 96, .......

Answers

The explicit formula for this sequence 6, 12, 24, 48, 96, .. is equal to aₙ = 6 * 2ⁿ⁻¹.

The sequence shown above is a geometric sequence because each term is obtained by multiplying the previous term by 2. To find the explicit formula for this sequence, we can use the formula:

aₙ = a₁ * rⁿ⁻¹

where:

aₙ = the nth term of the sequence

a₁ = the first term of the sequence

r = the common ratio between terms

n = the position of the term in the sequence

In this case, a₁ = 6 and r = 2, so the formula becomes:

aₙ = 6 * 2ⁿ⁻¹

Using this formula, we can find any term in the sequence by plugging in the value of n. For example, to find the 7th term, we would plug in n = 7:

a₇ = 6 * 2⁷⁻¹ = 6 * 2⁶ = 384

Which series of transformations can be used to justify that figure A is similar to figure B?

Answers

The series of transformations that can be used to justify that figure A is similar to figure B is: D. dilating figure A by a scale factor of 3 centered at the origin and then translating it up 2 units to create figure B.

What is a dilation?

In Geometry, a dilation is a type of transformation which typically changes the size of a geometric object, but not its shape.

In this scenario and exercise, we would dilate the coordinates of the pre-image (figure A) by applying a scale factor of 3 centered at the origin as follows:

(-2, 1) →  (-2 × 3, 1 × 3) = (-6, 3).

Next, we would apply a vertical translation 2 units up in order to create figure B;

(x, y)          →          (x, y + 2)

(-6, 3)         →          (-6, 3 + 2) = (-6, 5).
